在php中使用单选按钮值来显示三个div之一


嗨，我有一个下拉框系统，第一部分有三个伪装成图像的单选按钮。选择其中一个单选按钮后，我希望它能将下一节更改为相应的div（笔记本电脑、平板电脑或手机）。我困惑的部分是如何从单选按钮中获取值，而不必使用提交按钮。然后我想使用php来回显正确的div。我在想，在运行if语句比较单选按钮值后，我必须回显一个变量。我似乎找不到如何在不使用提交按钮的情况下触发脚本。

我不知道我应该使用什么类型的函数和方式，所以我不知道我用伪代码填充。

您可以获取单选按钮的值，并在jquery. click（）函数中对该值进行操作，例如：

$("laptop_button").click(function(){
    var radioValue = $(this).val();
    function_that_does_something_with_the_value(radioValue); // needs to be a javascript funtion
    $("laptop_panel").toggleClass("invisible");
});

如果您在单选按钮上包含值，如下所示，您实际上可以在每次单击/更改时提取值。

html

<input type="radio" name="type" id="laptop_button" value="laptop" />
...

<input type="radio" name="type" id="tablet_button" value="tablet" />
...

<input type="radio" name="type" id="phone_button" value="phone" />
...

  <button class="accordion type-accordion">
    <h2 class="text-center">
      Model
      <span id="selectedType"></span>
    </h2>
  </button>

代码

$("input[name='type']").change(function(e) {
  var selectedType = $(this).val();
  $("#selectedType").html(selectedType.toUpperCase());
}

并突出代码中的问题。下面的代码将不起作用，因为您错过了#ID选择。要在jQuery中选择ID（ID获取元素），您需要包含#tag。例如$（"#laptop_button"）

$("laptop_button").click(function(){
    $("laptop_panel").toggleClass("invisible");
});

$("tablet_button").click(function(){
    $("tablet_panel").toggleClass("invisible");
});

$("phone_button").click(function(){
    $("phone_panel").toggleClass("invisible");
});

只是为了好玩，我已经完成了您的屏幕类型和设备选择手风琴。 

$(".accordion").click(function(e) {
  $(this).toggleClass("active");

  var nextPanel = $(this).next(".panel");
  console.log(nextPanel);

  if ($(this).hasClass("active")) {
    // showPanel(nextPanel);
    nextPanel.showPanel();

    // hide default_panel when type is already selected
    if ((nextPanel.attr("id") === "default_panel") && ($("#selectedType").html() !== "")) {
      // hidePanel(nextPanel);
      nextPanel.hidePanel();
    }

  } else {
    // hidePanel(nextPanel);
    nextPanel.hidePanel();
  }

});


$("input[name='type']").change(function(e) {

  var selectedType = $(this).val();
  var selectedTypeID = "#" + selectedType + "_panel";

  $("#selectedType").html(selectedType.toUpperCase());

  // hide all device panel
  // $(".device-panel")
  // 	.hide()
  //   .each(function() {
  //   	hidePanel($(this));
  //   });
  $(".device-panel").hidePanel();

  // hide default panel if device type is selected
  $("#default_panel").hidePanel();

  // ensure that type-accordion button is always 'active'
  $(".type-accordion").removeClass("active").addClass("active");

  console.log("selected device type", selectedType, $(selectedTypeID));

  // showPanel( $(selectedTypeID) );
  $(selectedTypeID).showPanel();
});


// extend jQuery object
(function($) {

  $.fn.showPanel = function() {
    $(this)
      .show()
      .css("height", $(this)[0].scrollHeight + "px")
      .css("max-height", $(this)[0].scrollHeight + "px");
  };

  $.fn.hidePanel = function() {
    $(this)
      .hide()
      .css("height", "0px")
      .css("max-height", "0px");
  };

}(jQuery));


/* 
function showPanel(panel) {
  panel
    .show()
    .css("height", panel[0].scrollHeight + "px")
    .css("max-height", panel[0].scrollHeight + "px");
}
    
function hidePanel(panel) {
  panel
  	.hide()
    .css("height", "0px")
    .css("max-height", "0px");
